how do you put constraints? ? ? ?

Hello everyone, I have problems with a simple beam, directed along the x axis, hinged-pound subject to a uniformly distributed load
now in 2d know that the hinge blocks the translations long x and y and the support only blocks the long translation y
but when I make the model in patran, which is 3d, I have continuous problems of constraints that continue to give me fatal and when I can nn have the fatal stress obtained is wrong (this I know why I also did the calculations by hand)
Does anyone know how to solve the problem? ? ?

constraints a knot on 1,2,3,4
the other knot on 2,3
So you can fix it.
